Very steep, but not too long. Segment on Strava is called Witches Hill. Not sure where Lyndon is talking about, the one shown on the map here is public road, there are no gates which can be locked.

A Thankful Village is one that suffered no casualties in the First World War. Colwinston was one, though it lost four men in the Second World War.

It's a nice place, but when I was there, I had the impression that it was the favorite place of local retirees.

Rest Bay is a sandy beach on the outskirts of Porthcawl, backed by The Royal Porthcawl Golf Club. The beach receives a decent amount of swell, making it a good beach for surfing, as well as wind/kite surfing. Rest Bay has a café, and the town can be reached from here along a cycle path.
